Module 34: Multithreading in Java

🧵 What is Multithreading?

Multithreading in Java is a process of executing multiple threads simultaneously. It helps in performing multiple operations at the same time and improves the performance of the program.

🔧 Creating Threads in Java

• By extending the Thread class
• By implementing the Runnable interface

📌 Example 1: Extending Thread Class

                    class MyThread extends Thread {
                      public void run() {
                        System.out.println("Thread is running...");
                      }
                    
                      public static void main(String[] args) {
                        MyThread t1 = new MyThread();
                        t1.start();
                      }
                    }

📌 Example 2: Implementing Runnable Interface

                    class MyRunnable implements Runnable {
                      public void run() {
                        System.out.println("Runnable thread is running...");
                      }
                    
                      public static void main(String[] args) {
                        Thread t1 = new Thread(new MyRunnable());
                        t1.start();
                      }
                    }

• New
• Runnable
• Running
• Blocked/Waiting
• Terminated
